Is this a software error in the 3k_V1_1_Room.spn program

Post by scmitche »

Hi Frank,
I'm slowly learning to program the FV-1 and came across this snippet of code from the 3k_V1_1_Room.spn program written by Keith Barr I believe.

;prepare decay pot:

rdax pot1,0.97 ;get pot, limit to less than infinite
wrax krt,1 ;write loop decay time
sof 0.4,0.6 ;scale to 0.6 to 1.0
wrax kirt,0 ;write impulse filter gains
sof -1,0.99 ;scale to decrease gain with RT
wrax gain,0 ;write gain factor

Is the wrax kirt,0 command correct, which I think clears the ACC before the following sof -1,0.99 command? My thoughts are that it should read wrax kirt,1, am I correct?
Regards,
Steve

It could be, I did not write that code so I do not know if it is a typo or if he changed his mind while writing it. Try changing it and see what happens.

Thanks Frank. I changed the code but found that the -1 needed changing to -0.95 and then it worked well with a calculated gain factor reducing from 0.42 to 0.04 as the reverb time increases with Pot2 sweep.
It sounds nice now, as good a reverb for guitar as I've heard in quite some time.

Regards,
Steve
